terminal_cd · Global MCP Manager MCP: Risk & Policy

WHAT IT DOES

What terminal_cd does on Global MCP Manager

AI agents invoke terminal_cd to trigger actions in Global MCP Manager. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why terminal_cd needs a policy

The tool name 'terminal_cd' strongly suggests a change-directory operation in a terminal context. While changing directories is generally low-risk on its own, within this server's context of executing terminal commands across local, SSH, and remote environments, navigating directories could be a precursor to or part of broader execution workflows. The description is empty, lowering confidence.

From the tool's definition Tool name 'terminal_cd' on a server described as enabling 'executing terminal commands' across local, SSH, and GitHub contexts

Verdict

terminal_cd Rate-limited

terminal_cd stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
